Transcription

1 Lung Pathway Group Carboplatin & PO Vinorelbine in Non-Small Cell Lung Cancer (NSCLC) Indication: First line in radical/induction treatment in locally advanced NSCLC First line palliative treatment in advanced/metastatic NSCLC Eligible for patients able to tolerate and comply with oral dosage forms Regimen details: Carboplatin AUC 5 (EDTA) IV Day 1 Vinorelbine 60mg/m 2 PO Day 1 & Day 8 (first cycle) *Vinorelbine 80mg/m 2 PO Day 1 and Day 8 (second cycle onwards) * See dose escalation guidance under Dose modifications - Note: Vinorelbine dose escalation is not indicated in advanced disease or palliative treatment intent, unless vinorelbine is used as monotherapy. Concomitant with radiotherapy**: Carboplatin AUC 2 IV Day 1 Vinorelbine 60mg/m 2 PO Day 1 and Day 8 (first cycle) **When combined with radiotherapy, vinorelbine and carboplatin doses are reduced. Dose escalation to 80mg/m² does not take place with concomitant radiotherapy; when combined with radiotherapy, vinorelbine dose is reduced to 50-75% dose, depending on clinical oncologist s recommendations. 2 or 3 cycles of radiotherapy may be given concomitantly with chemotherapy. Administration: Carboplatin in 500ml Glucose 5% over 60 minutes Aluminium containing equipment should not be used during preparation and administration of carboplatin

2 Vinorelbine available as 20mg, 30mg and 80mg soft capsules. Capsules to be swallowed whole with water without chewing or sucking. Capsules are recommended to be taken with food. Hypersensitivity reactions may occur, such as flushing, rash with or without pruritus, chest tightness, back pain, dyspnoea and fever or chills, usually during the first and second infusions and within a few minutes following the start of the infusion; the infusion should be slowed down or interrupted and the necessary supportive medication should be administered. Severe reactions such as hypotension and/or bronchospasm or generalised rash/erythema requires immediate discontinuation. Availability of resuscitation equipment must be ensured as a standard precaution. Frequency: Induction/adjuvant Advanced/palliative Pre-medication: Anti- emetics: Supportive medication: Extravasation: Day 1 and Day 8, every 21 days Total of 4 cycles; 2 to 3 cycles may be given concomitantly with radiotherapy Total of 4 to 6 cycles Not routinely required Day 1: High emetogenicity Day 8: Low emetogenicity Follow local anti-emetic policy Mouthcare as per local policy Paracetamol / Chlorphenamine / Hydrocortisone can be given for administration-related reactions such as chills / fever. Carboplatin is non-vesicant Regular investigations: Prior to Cycle 1: FBC LFTs U&Es CT scan EDTA Day 1 (within 14 days) Day 1 (within 14 days) Day 1 (within 14 days) Baseline See comments

3 Comments: Carboplatin dose should be calculated using the Calvert formula: Dose = Target AUC x (25 + GFR). GFR should be calculated using EDTA clearance before prescribing. (If EDTA not available prior to cycle 1, initiate treatment using the Cockcroft & Gault formula to calculate GFR, and ensure EDTA prior to cycle 2). Monitor trends in serum creatinine between treatments, if >25% from baseline value re-calculate GFR using the Cockcroft & Gault formula or EDTA. Prior to Day 8 (all cycles): FBC Prior to Day 1 (all cycles): FBC LFTs U&Es Imaging* Day 8 (within 48 hours) Day 1 (within 72 hours) Day 1 (within 72 hours) Day 1 (within 72 hours) After 3 cycles *Imaging is not required in the adjuvant setting Toxicities: Myelosupression, ovarian failure/infertility, peripheral neuropathy and neuropathy induced constipation, alopecia (usually mild), GI symptoms, nausea and vomiting, myalgia, fatigue, neurotoxicity (ototoxicity), nephrotoxicity, encephalopathy, electrolyte imbalances. DOSE MODIFICATIONS Haematological Toxicity Prior to day 1 Neutrophils Platelets Carboplatin Dose Vinorelbine Dose (x 10 9 /L) (x 10 9 /L) 1.5 & % dose 100% dose < 1.5 &/or < 100 Delay for 1 week. Repeat FBC, if recovered to above these levels give 100% dose. Delay for 1 week. Repeat FBC, if recovered to above these levels give 100% dose. If neutrophils < 0.5 x 10 9 /L for more than 5 days or < 0.1 x 10 9 /L for more than 3 days, or platelets < 25 x 10 9 /L, or febrile neutropenia is diagnosed, or toxicity related delay is > 1 week - vinorelbine dose should be reduced to 75% from previous dose (do not escalate for subsequent cycles).

4 Prior day 8 Neutrophils (x 10 9 /L) Platelets (x 10 9 /L) Vinorelbine Dose 1.0 & 100 Give 100% dose < 1.0 or < 100 Omit Vinorelbine Dose escalation after 1st cycle in Adjuvant/ Induction setting (not for RT patients) If the first cycle is well tolerated, it is recommended to increase the dose of vinorelbine to 80mg/m 2 at cycle 2 in the following settings: Adjuvant/ induction setting, and when vinorelbine is used as a single agent. When relevant, dose escalation should take place at cycle 2 only if: o no grade 4 neutropenia (<0.5 x 10 9 /L) at day 8. o no febrile neutropenia Dose escalation should NOT occur in the palliative treatment of advanced disease unless vinorelbine is used as monotherapy, or for patients who are having concomitant chemotherapy regimen. Vinorelbine Dose de - escalation from 2 nd cycle onwards in Adjuvant/ Induction setting If grade 4 neutropenia (<0.5 x 10 9 /L ) occurs during cycles with 80mg/m 2 dose, delay treatment until recovered, then reduce to 60mg/m 2. It is possible to re-escalate the dose after further 3 administrations with lower dose if well tolerated. Follow monitoring in following cycles as detailed above. Non-haematological Toxicities Renal Impairment Creatinine Clearance (ml/min) Carboplatin Dose 20 Give 100% dose < 20 Contraindicated Vinorelbine: Dosage adjustment not required Hepatic Impairment Carboplatin: Dosage adjustment not required Vinorelbine: If hepatic insufficiency is due to metastatic involvement, liver function may recover in response to treatment. Therefore, for patients with massive liver metastases, i.e. >75% of liver volume replaced by tumour, it is empirically suggested that the dose of vinorelbine be reduced to 85% dose and haematological toxicity closely followed up. If hepatic insufficiency is due to other reasons, the table below should be used:

5 Bilirubin ALT / AST Vinorelbine Dose < 1.5 x ULN < 5 x ULN Give 100% dose x ULN 5 20 x ULN Delay day 1 for 1 week/omit day 8, and reassess*. Consider dose reduction to 25-50% dose. > 3 x ULN > 20 x ULN Discontinue *If liver toxicity persists for more than 3 weeks, discontinue treatment Dose modifications for other toxicities as appropriate Neurotoxicity Neurotoxicity Carboplatin Dose Vinorelbine Dose Grade 2 Give 50% dose Give 100% dose Grade 3 or 4 Discontinue Other toxicities Carboplatin Dose Vinorelbine Dose Grade 3 mucositis Give 100% of previous dose Give 75% of previous dose Grade 4 mucositis Give 75% of previous dose Give 50% of previous dose Any grade 3 toxicities Give 75% of previous dose Give 75% of previous dose (except mucositis) Any grade 4 toxicities (except mucositis) Give 50% of previous dose Give 50% of previous dose, or omit if Day 8 dose Diarrhoea (any grade) Give 75% of previous dose Give 75% of previous dose requiring hospitalisation Grade 3 oesophagitis with radiotherapy Delay for 1 week, continue radiotherapy if possible Grade 3 or 4 constipation Omit consider substituting with gemcitabine If patient suffers any Grade 3 or 4 toxicity after 2 dose reductions, treatment must be reviewed by consultant Location of regimen delivery: Comments: Day case setting Women of childbearing potential must use effective contraception during treatment. Sexually mature males are advised not to father a child during the treatment, and up to 6 months thereafter. If appropriate, male patients should be advised to seek counselling on sperm storage before starting treatment.
